How can I have icons on yahoo page for colors,highlighter,bold letters and font changes? when I compose email?

You need to enable the formatting bar.





On mail page, click on "options" (upper right)---then scroll to and click on "general preferences".


Now, go down to *Composing Emails* and check the button by-----"compose with color and graphics"----then click "save" at bottom of page.





If you're using Beta or New mail----there is a link on the composing page (end of subject line, I think)------"Rich Text or Plain Text-----that will enable or disable that bar.
